1.3.6. What are the names of the Japanese non-kana, non-kanji symbols?

It's quite difficult to find out the names of the common
non-kanji and non-kana Japanese symbols. These symbols are
called yakumono (約物) in Japanese. Here is a table of symbols,
the hexadecimal JIS code and Unicode for the symbols for computer
input, and the names for the symbols.

This is the kunojiten mark with dakuten. The dakuten applies
to the first character of the word. For example, tokorodokoro
could be written vertically as ところ plus this mark. Note that one
symbol requires two Unicode characters.

Repetition marks

The repetition symbols described here are much less used nowadays than
they were in the past. Odoriji (踊り字) and jōji (畳字),
also known as hanpukukigou (反復記号) are general names for the
repetition marks like 々 and ゞ. On a word processor, they can be
obtained by typing dou (同), onaji (同じ) or onajiku (同
じく). See also 14.4. How can I input small kana like ぃ, っ and ょ, or づ on a computer?
